摘要: A gas replacement process and a gas replacement apparatus are employed, in the nitro compound hydrogenation reaction process. The gas replacement process at least includes a first step of subjecting a stream to be replaced to the gas replacement in presence of a first replacement gas, and then a second step of subjecting to the gas replacement in presence of the second replacement gas. Assuming the superficial velocity of the first replacement gas is V1, and the superficial velocity of the second replacement gas is V2, then V2/V1≥1.5.

摘要: A biphasic solvent system for converting biomass to prepare 2,5-hexanedione and a one-pot process for catalytically converting biomass to prepare 2,5-hexanedione with said biphasic solvent system are provided. The process includes the steps of contacting and reacting a biomass raw material with a hydrogenation catalyst using hydrogen gas as a hydrogen source in a heterogeneous system formed from an organic solvent, an inorganic salt and water to obtain 2,5-hexanedione. The hydrogenation catalyst includes a hydrogenation active component and a support. The support is selected from one or more of hydrophobic active carbon and graphene. The process can achieve efficient conversion of biomass without the participation of acid catalysts, and have a very high selectivity for the product 2,5-hexanedione.

摘要: A lithium battery positive electrode material precursor and its preparation method and application are provided. The positive electrode material precursor has the chemical formula NixCoyMzTp(OH)q and contains secondary particles in the form of microspheres formed by agglomeration of primary particles. The microspheres have a three-layer structure from the inside to the outside, namely an inner core layer, a middle layer and an outermost layer. The ratio of the intensity of the (110) and (102) crystal planes diffraction peaks expressed as peak height in the XRD diffraction pattern of the inner core layer of the microsphere is 1.0-8.0. The positive electrode material prepared by using the positive electrode material precursor has high discharge specific capacity and good cycle stability and can be used in high-performance lithium batteries.
